You know... Eastwoodco.com has a great gas tank coating kit for $34.
Complete instructions on how to clean the tank for the coating too. First
it's hot soapy water,rinse, followed by the included Metal Wash which
dissolves the varnish, rinse, then Muratic Acid, rinse, then acetone and the
coating. The interior of the tank before starting this procedure was much
like you wrote... afterward, it was shiny metal before I coated it. My
entire cost was about $50. Getting rid of the used materials was probably
the worst. This is my third tank I have done like this and so far no
problems...
Good luck!
